The issue I have with Kincaid so far is that when he is split out wide, a safety or CB neutralizes him easily. When he is lined up in line, he has more success on routes where a LB needs to pick him up. But he can't block, so you can't rely on him in the run game like you can with Knox. Coming out, he was touted as a complete player who catches everything and can block, but that wasnt really the case last year.
The good news is he stands to benefit from another year in the system, removed from his injury, and with Cook emerging as a talented back.
